To all iii/1 0m it may concern: I 1

Be it known that I, JOSEPH IMPELLIZIERI,

a subjectof the King ofItaly, and a resident the city of New York, borough of Brooklyn, in the county of Kings and State'of New York, have. invented new and uSefuI Improvements in Power-Transmission Mech anisms, of which the following is'a full, clear and exactdescrlption.

This invention relates to power transmis-.

, forrepairs or'for'replacement considerable T showing its construction;

care has to be chine.

The general object ofjthis invention is the provision of a simplea'nd' durable power transmission device that may be mounted: in conjunction with any'machine and adj usted to transmit power along different lines. A further object of the invention, is the provision of a power transmission device, the gears and clutch wheels of which are so mounted that they areheld againstrmovementlengthwise of their shafts.

These objects are accomplished by providing a supportingplate on which a frame is so mounted that it maybe rota'tedin alplane parallel to the supporting .plate so as to receive, and transmit: power along different lines." w

These and other objects'of the invention will be more clearly understood from" the following detailed description and accompanying drawings.

Figure l is a side elevation of a power transmission device with a Figure 2 isa sidelelevation of a modification of the power transmission device Figure 3 is a section along the.li ne; 3-'3,

Figure lan. view of the supporting" taken in mounting the mag part in section,

plateshowingthe adj ustably' mounted thereon.

Referring to the above-mentioned draw .ings a plate 10 is shown'with the S I PPOrtr" ing plate 11- attached thereto by means of bolts 12. Mounted on the supporting plate 11 is a framelfiprovided withfour lugs 17.

This frame is attached to'thesupporting v plate bymeans of bolts 13 which are slidably mounted in arc-shapedslots 18 cut inthesupporting platellg'. The frame 16 is provided with iJWO'fiIII'lS l9 and 20 which ex tend parallel to one another.

The arm 20 has an opening extending therethrough in which bushing 21 is" mounted. This bushing 21 is attached to the arm 20 by means of set-screws 22. "Attached to the arm QOby-ineans ofbolts 23 is an annular plate 24, the internal diameter of which is equal to the]iI' terna-l', diameter of the bushing I This annular plate is located between the arms19 and 20. A-hol low axle 26 provided witha grease, Cup 27 which communicates with the axle/chamber isjslidably mounted in the bushing '21 and the annular plate 24. Thisja'xle is held against rotation by thelpr ojection 57 formed integral with the axle and adapted for engagement' with the bolts QESY'Perforations 28 are provided ,in the hollow axle 26 for lubricating purposes. Formed on one'end of the. axle 26 is a head 25, the diameter of which is equal to the internal. diameter of the hub of a pulley 29. This-pulley 29 is mounted onthehead and a bushing 30 mountedon the axle 26 isfitted into, thehub of the pulley andjattached thereto "by set screws-31 m reta'in the pulley in position On'the axle. A; friction ring' 32 is mounted on the face ofjthe pulley 2 9 collar is attached to the axle 26 andserves to limit the movement of the axle in one direction. A

coil spring, is mounted on the axle 2G and interposed between the'annular plate 24 and p the collar 33 to normallyretain the friction ring mounted on the-pulley 29 outofengage- Inent with, the driven gear to he described in asubsequent"par'agraphQl 20 at 36 has adepending armSTin which an adjustable pin 38 is mounted, Thelever 35 is operated by means of a-" treadle.39 and 1 a connecting rod; 40. Byoperating the lever arm the pin 38 is force'cl in'to engagement I v with the axle 26, forcing it endwise, carrying the friction ring 32 into engagement with a gear to be'descrlbed in a subsequent paragraph. Integral with the lever 35 is a brake 41 which engages with thepulley to stop its rotary motion. A plunger15 is supported in alinementwith the brake 4C1 by means of a U-shaped member 14 carried by the plate 10 and extending through. an opening 43 in the supporting plate 11 and into" :an opening 4 1 in the frame 16. A

, 4E5 provided with spring 12 is mounted. on the plunger 15 and serves to forcejt downwardinto' engagement with the brake 4- 1. so

.Carried by the arm 19 is ahollow axle a grease cup 16 which communicates with the axle chamber. This axle is mounted in alinement with the axle 26fandhas mounted on one end a bevel gear -meshes withthe gear 457. p

transmission shaft is supported by a cap along different lines.

47' provided with a friction face 48 Thisv gear ismounted in a' manner similar to that described for the pulley 29. A bevel gear 49 carried by a transmission shaft 50 which is associated with the 'main drive shaft The end of the 51 in which a bearing for the end of the shaft 50'is provided. This cap 51 is attached to the arm 19 by means of the set screws 52. By removing the set screws the cap 51 may be rotated about the axle 15 in a plane at right angles to the axle thus allowing the shaft 50 to berotated so as to transmit power When it is necessary 16 through anangle ofi180 from the position shown in Figurel, a bell crank, 53 is pinned to the arm 19 at,5l-,.-and the pin 38 is then mounted in the depending farm of the bell Icrank. :The lever a; rarryingthe 1 brakell has an extension 56 attachedto it.

, it is desired to receive power from the shaft 50 extending at an angle to the horizontal the cap is rotated until'thebearingcarried by it is in alineme'nti witlrthe sli'aft 50 so as to receive the same. Thejgea-rs 9 "and 457 are operated-through the shaft 50. WVhen it is. desiredto transmit. power from the shaft 50 through the devicearranged shown in Fignre-l g the treadle 39 is operated. removing, the brake {11' from pulf ley 2 9 afid'rorcing aiepin 38 into engage to rotate the frame ment with the axle 26, forcing it endwise in the bushing 21 and the annular plate 24.

This-brings the friction ring 32 into engagement with the friction face 18 of the gear &7, and the pulley 29 which carries the belt 58 is operated. hen the treadle S9 is released,-the spring 34 forces the axle 26 to theleft, raising the lever 35. The plunger 15 now acts,forcing the brake ll into engagement with the pulley 29, its motion. e

When the device is arranged as shown in Figure 2, the axle 26 is operated through the bell crank 53. v

L would statein conclusion that while the illustrated examples constitute practical embodiments of my invention I do not limit serving to stop myselfstrictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as defined in the appended claims.
